IMPROVEMENT IN BINDING ATTAQHMENTS 'To'HARvE's'TERsQ Specification formi-12g part of Letters Paton-t No. 39,510, dated August `11, Y

To all whom 'it may concern Be it known that I, ALEXANDER UNDER- WooD, of the city and county ci`Kenosha,'.

in the State' oi' Wisconsin, have invented n. new end improved machine or combination of machinery for raking and binding groin;l and I do hereby declare that the following isa full, clear, and exact description of tl1econ-- struction and operationof the same, reference being had to the accompanying drawings,

making part of this specification, in whi.ch-

Figure l is e, perspective'view of :in` auto metio raking and bindingepperatus, embracing my improvements. Fig. 2is e perspectivev viengzfrom the under side ofthe pl'etfornn'of a .part of the bindingmechincry. Fig, 3 is e 'perspective view'(i`ronr 'the left-hand corner andunder side of' Fig. 1) of the other portions of the binding mechanism, hereinaftertobe of the endle'sschain rake'. Figs, Z, 8, andi) are diagrams illustrating the form and oper-- ation ot' certain coms, hereinafter to be described,

' The 'subject of my invention is n machine# which may be attached to the side or` rear of a. harvesting-machine of any form, to automaticnlly gevelV the grain es fast as cut, and bind and discharge it in sheaves of :my desired size; l

The invention particularly consists, -lirst, Ain devices' for .passing the cord around the sheaf; second, in `devices for securing and tying the band; third, in devices for throwing the mech` anism in and out of gear. A y

Theiendlesschaiu rakes, as shown et b b f e, Fig. 1, and f e, Eig. 6, are constructed of two series of metal 'platesLriveted or screwedto gether, with angular-shaped' teeth hungloosely between them etv intervening distances, as

Thus, asthe grain' is ,out -andfnlls 'upon `the f platform, it is conveyed to the box or trough and rolled up into la.4 gevel directly under the raises O and y'. P is e counter-shaft.

5. The combination. of the hooks l2 r, re dimly-slotted pinion o2, sliding bar C, and

shear-blades h3 and n, whenthe said parts are' constructed and arranged in the manner hereinnefore described, so es to adapt there to uniformly twist and. subsequently knot ond sever the band. l

6. The sind is, operated by the sliding bar C, and employed, in the described combination with the sheer-blades k3 and n, to hold the said blades' in close proximity and retain the end of the cord, es explained. i

7. The combination, with the gear-wheel G, sliding bar G, stud k, and loledes lia rind d, of

the roller el, grooves .s g1, shifting curved in-f elined piane t, and spring-stop z, operatingl es explained, to impert en alternate inotion to the ber G to sever the cord en one or other brancln of the blade n.

8. The combination, with the gear-wheels i, F, ,and G, of the clutch-pinion V, clutch d. cemsf1 o, lever g2, andd'og r2, whereby en intermittent motion is imparted to the wheel G end thedog r inserted in and retracted from e. notch therein, as explained.
